Abstract

PURPOSE:To enhance the operating efficiency of the rotary electric machine and to obtain the stable control thereof by allowing the field current occurred within predetermined time even if it exceeds the maximum allowable current and thereafter returning stepwisely to normal control state. CONSTITUTION:If the deviation signal 7a between allowable field current 8a and field current 6a exceeds the maximum allowable deviation value V0, a monostable circuit 17 is energized so that the contact 7a is opened. Thus, the integrator 15 integrates the deviation signal 7a at a time constant responsive to the value of the deviation signal 7a. If the output 15a of the integrator 15 exceeds the set value 21a, monostable circuits 22, 23 are energized, the deviation signal 7a is stepwisely converted to stepwise signal, then is applied as excessive excitation limit signal to the automatic voltage regulator 3. Thus the shock occurred at the generator is alleviated when the excessive excitation limit is applied thereto.
